Specifications
Light Burnt Magnesium Oxide Ball
1.Stable quality performance
2.Protect the furnace
3.Reduce consumption
4.MGO:65%
Advantage and Application
The advantage of this new material is its high MgO content as well as burned substances,which can also avoid with in furnace decomposition burning so as to save much energy. By this new means,it will do a lot good for improving the rate of scrap steel and sand melting. It is used for converter steel making,through the splashing cross to protect the furnace,which can raise the furnace life.
Because slag splashing furnace protection requires appropriate viscosity and refractoriness, reasonable slag content is the key for slag splashing furnace protection. Common slag can’t be applied to slag splashing furnace protection directly, a certain amount of caustic calcined magnesia balls need to be added to adjust, meanwhile replacing the usage of dolomite, reducing the quantity of slag, increasing MgO content in slag. Because MgO is a mineral with high melting point of 2800°C, by increasing the MgO content in slag, the viscosity of slag and refractoriness will also be increased, which will make it easier for the slag combine together with the linings and form an effective slag protection layer, thus improving the service life of linings and reducing consumption.

- Q: What kind of material is good for cabinet fireproof board
- Natural stone marble: Advantage： Rich color, texture is more soft, easy for cutting or molding; shortcomings: Because it is a natural formation, micro cracks will get easily broken. If sewage infiltrates in during production and transportation, it is difficult to clean and it will get cracked. In the daily cleaning, residue will be filled into the cracks when using cloth to clean. then the material will become breed bacteria. In the long process of the formation, natural stone material may cause harm to human health due to the formation of heavy mental which is radioactive.
- Q: How to divide the materials according to the National Fireproofing Material Standard?
- according to China's national standard GB8624-97, the combustion performance of construction materials can be divided into several classes: Class A: Incombustible building material: Almost no burning material. Class B1: nonflammable building material: nonflammable material has a good flame resistance effect. when it meet the open fire in the air or burnd at high temperature, it is difficult to spread quickly, and when the fire source is removed, the combustion stop immediately. Class B2: flammable building material: flammable material has a good flame resistance effect. when it meets open fire in the air or at high temperature, it will immediately burst into flames and easily cause fire spread, such as wooden column, timber roof truss, timber beam, and wooden stairs,ect.. Class B3: inflammable building material: No flame resisting effects, highly flammable, high fire risk.
- Q: What are the standards of refractory concrete ?
- Refractory concrete is generally divided into three categories: Light insulating concrete (for insulation); medium-quality refractory concrete (It is used for the parts where requirement of refractory temperature is not very high, and it can withstand a certain erosion of air); heavy refractory concrete (It is used for the parts where requirement of refractory temperature is fairly high, and it can withstand a certain intensity of erosion of air). It mainly depends on the design temperature and the using parts. There are a variety of raw materials, of which aluminum oxide is one of the most commonly used materials, others are alumina hollow ball, magnesium oxide, zircon, etc. It depends on the design temperature and the parts on use. Commercial concrete station generally can not produce it, instead it is compound by professional refractory concrete factories.
- Q: What are included in roof thermal insulation fireproofing material?
- Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire?retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.
- Q: What kind of materials can be tested their electrical resistivity in the current refractory industry?
- Graphite, Magnesium Oxide, and alumina are all feasible.
- Q: Refractories for iron-making blast furnace?
- Vibrating materials, corundum brick and aluminum carbon brick will be developed. Taphole commonly use stemming, silicon carbide - graphite bricks, whose material is Al2O3-SiC-C. Medium and large sized blast furnaces in China use dense mullite bricks, castable, graphite brick. Common lining material for iron ditch is ramming mass. hearth and furnace bottom common use carbon bricks, semi-graphite bricks, charring silica bricks, corundum bricks. Blast furnace bosh and lower part of furnace stack commonly use mullite bricks.
- Q: Is there anyone who can explain how to grade the level of fire insulation board?
- 1, Combustion performance of building material is divided into the following several class according to China's national standard GB8624-97 Class a: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect. It hardly catch on fire in the case of open flame and high temperature, do not spread fire quickly, and when the fire source is removed, fire will be stopped immediately. Class B2: Combustible building materials: Combustible materials have certain flame retardant effect. In case of fire or under high temperature, it will immediately burst into flames, easily leading to spread of fire , such as poles, wooden frame, timber, and wood stairs. Class B3: Combustible building materials: Without any flame retardant effect, will be burnt easily, resulting in high risk of fire. I Hope my answer will help you.
- Q: What types does refractory floor include?
- There are many types refractory bricks, including silicon aluminum refractory brick, the leading product in refractory bricks. And its high temperature resistance can reach up to 600 degree centigrade or more, so it is an excellent refractory brick. And this high-alumina refractory brick is very suitable for metal industry for its strong practicability. Another one is alkaline series refractory brick, including magnesite refractory brick, and these two bricks are good materials resistant to high temperature.
- Q: How to make the service life of refractory materials longer?
- Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
- Q: Does anyone knows which company produces the better refractory materials?
- A:Building Materials Company of Guangzhou: Near the Baiyun District, Baiyun District, Guangzhou Road, North Road. B：Guangzhou Research & Development Co., ltd.: Liwan District Fengyuan road No.90 in Guangzhou City C: Huitailong decoration materials Co., Ltd.：the 30th floor of No. 111 Pacific Center, Taikang Road, Yuexiu District Guangzhou City D：Guangdong metal materials company: Near Qishan Road, Tianhe District , Guangzhou city.
